Description

I'm not totally sure if this is a bug or a feature, but you cannot build individual modules without first building/installing the parent. Among other things, this makes it difficult to work with groups where some modules are not compiling.

For example, using the j2ee-simple archetype:

$ mvn archetype:generate -DgroupId=com.example -DartifactId=example -Dversion=1.0-SNAPSHOT -DpackageName=com.example -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-j2ee-simple

On the other hand, this works fine (once you remove the missing site module):

cd example
mvn3 install
